Background and Objectives Most renal patients have various oral manifestations such as halitosis, xerostomiaand pale mucosa. The purpose of this study was to evaluate the relationship between periodontalstatus and chronic renal disease.Subjects and Methods In this case-control study, the case group was divided into three subgroups, whichincluded renal patients before dialysis, patients undergoing hemodialysis, and patients after renal transplantation,each of which included 23 patients. The control group also included 38 healthy individuals interms of renal function. After obtaining the consent form and completing the questionnaire, the amountof plaque index, gingival index, papillary bleeding index, probing depth, loss of clinical attachment, gingivalrecession and gingival enlargement were measured T-student,chi-square. and Anova was used toanalyze the data.Results The plaque index, gingival index, papillary bleeding index, probing depth, loss of clinical attachmentin groups with chronic renal disease were higher than the control groups (P< 0.001) but there wasno significant difference in gingival recession and gingival enlargement between control group and casegroups (P> 0.05 ) . These parameters were not significantly different between the groups with chronicrenal disease (P> 0.05).Conclusion Periodontal disease is more common in patients with chronic renal disease, therefore, specialperiodontal treatment considerations and regular dental examinations should be added to the treatmentplan of these patients.

Periodontitis is an inflammatory disease that involves supporting tooth structure,can be affected by risk factors like smoking, and increase the prevalence and severity of periodontal damages.Antioxidant stress to target molecule and prevent from degeneration of normal cells. This study aimedto compare the salivary total antioxidant level in smokers and non-smokers with chronic periodontitis.

A case-control study was performed in 60 chronic periodontitis patients (30 smokersand 30 non – smokers) in referral patients to Ahvaz Jundishapoor university of Medical Sciences,School of Dentistry. Saliva samples were collected from all subjects and the total salivary antioxidantlevel in these subjects measured with the spectrophotometry method in 600 nm wavelength. data analyzedwith t-test statistical analysis.

A significant difference between total salivary antioxidant level in smokers and non-Smokers patientswith chronic periodontitis observed (P<0.001).

This study showed decreasing in total salivary antioxidant level in the smoker- patients withchronic periodontitis compared to non-smoker patients with chronic periodontitis.

Recently, there has been an increasing growth in research on medical plant’s effect on dental plaque bacteria. The aim of this study was to determine the antibacterial effects of Satureja hortensis extract and its essential oil (EO) on Streptococcus salivarius¸ Streptococcus sanguis, and Streptococcus mutans as important bacteria in early supragingival dental plaque formation. In this in vitro study, different concentrations of S. hortensis extract and its EO were prepared using double dilution method. The disc diffusion method was used to determine antibacterial activity. Based on these measurements, the minimal inhibitory concentration value was reported for each bacterium. Antibiotics used as positive controls in this study were erythromycin (15 μg) and tetracycline (30 μg). t‑test and ANOVA were used for statistical analysis (P < 0.05). Aqueous and methanolic extract did not show significant antibacterial activity, but the EO significantly inhibited the growth of the test bacteria compared to positive control (P < 0.05). High concentrations of EO processed greater antimicrobial effects against three oral bacteria than other low concentrations (P < 0.0001). For S. mutans, the inhibition effect of tetracycline 30 µg was similar with 50% (P = 0.789) and 25% (P = 0.158) dosages of the EO. For S. salivarius, the effect of tetracycline 30 µg was similar to 50% dosages of the EO (P = 0.122). For S. sanguis, the effect of erythromycin 15 µg was lower than 50% (P = 0.0006) and 25% (P = 0.003) dosages of the EO. The inhibition effects of all concentrations of EO were higher for S. sanguis. S. salivarius and S. sanguis are more sensitive than S. mutans to S. hortensis EO. Due to the strong antibacterial effect of S. hortensis EO on the oral bacteria growth, it can be served as herbal mouth rinse, while to confirm this antibacterial effect, further clinical studies are necessary.

Increase in free radicals leads to oxidative stress which is implicated in the pathogenesis of many systemic and oral diseases such as periodontal disease. The aim of this study was to find the relationship between the salivary total antioxidant level and periodontal disease.
Subjects and This case control study included 15 patients with periodontitis, 15 patients with gingivitis and 15 controls were recruited from patients referring to Ahwaz Dental School in 1390-1391. The levels of salivary total antioxidants were evaluated using Spectrophotometry method. Control group had significantly higher total salivary antioxidant level compared with patients with gingivitis and periodontitis (P<0.001).The difference between total salivary antioxidant level in patients with gingivitis and periodontitis was not significant (P>0.05). The findings demonstrate an inverse relationship between total antioxidant level with development of periodontitis and gingivitis

Efficient diagnosis of allergy and proper treatment need identification of the causative allergens eliciting clinical symptoms. The present study was designed to identify the most common aero- and food allergens and determine the pattern of sensitization among people of Ahvaz (southwestern Iran), one of the most polluted cities worldwide. Based on the medical examination and a detailed questionnaire, patients were referred to the Allergy laboratory for “in vitro” IgE determination. Specific and total IgE was determined by the ImmunoCAP system (Thermo Fisher-Phadia, Uppsala, Sweden). A total of 666 consecutive patients (51.1% female) were tested for 202 different allergens. The majority of requests (57%) belonged to food allergens. Sensitization to at least one allergen was found in 47.6% of patients. In a selected group of allergens for which specific IgE had been tested in at least 100 patients, the most common sensitizing aeroallergens were Russian thistle, grass pollen, and willow; while wheat, honey, and shrimp were the most frequent food allergens, respectively. Sensitization profiles based on measurement of specific IgE indicated that Russian thistle, grasses, and wheat were the most prevalent allergens in people with allergic symptoms living in Ahvaz.

This study was performed comparing the degree of extrinsic dental stain removal for three dentifrices: (1) an Iranian (2) commercially available whitening dentifrice and (3) commercially Regular. A total of 75 participants were contribute into the study and stratified into 3 groups and randomly assigned to use one of the three dentifrices. Participants were instructed to brush their teeth twice daily (morning and night) for 2 minutes with their assigned dentifrice and available toothbrush. Stain area and intensity was assessed using a modification of the Lobene indexin the beginning of study،4 and 6 weeks intervals. Collected data analyzed using Kruskal Walis and BonFerroni method. A total of 75 patients were contributed in this study. Iranian whitening toothpaste and commercially were more effective than control toothpaste in removal of stain from all sites. There was no significant difference between two groups of commercially and Iranian dentifrice. This study showed that Iranian and commercially whitening dentifrice had a significant effect on reducing tooth staining.

Backgrond and There is inconclusive evidence about the relationship between toothbrush wear and plaque removel. The aim of this study was to compare the effectiveness of new and 3 month-old toothbrush in the removal of dental plaque. In a randomized single blind clinical trial 63 students attended from Awaz Dental School. Subjects were divided to three groups. Plaque was scored pre-brushing and post brushing new toothbrushes using the Turesky et al index. After 3 months، plaque was rescored pre-brushing and post-brushing 3-month–old brushes following 48h periods of no oral hygiene. Collected data analyzed using Paired-t-test and ANOVA. All 60 subjects compelated this study. Both the new and 3-month-old brushes reduced plaque scores significantly than pre-brushing time. The percentage reductions in plaque scores achieved with the new brushes were not significantly different from those achieved with 3-month-old brushes from total surfaces. Compared with 3 type toothbrushes، no significant different were found for plaque score reduction with the new and 3-month-old brushes. This study found that 3-month-old toothbrushes were as effective as new brushes when used 3 brands toothbrush to removal of dental plaque.

Based on the latest researches it is concluded that periodontal disease is an important risk factor, leading to preterm delivery low birth weight babies and the effects of socioeconomic status on periodontal condition. The aim of this study, evaluation of periodontal condition of pregnant and non-pregnant women based on CPITN index and relation between the demographic and clinical variables. Subjects and A cross–sectional descriptive study was carried out among 540 pregnant and non-pregnant women. Data collection was carried out with a questionnaire with demographic and clinical variables. Examinations were performed with WHO probes and dental mirrors. Data were analyzed by the means on Chi-square T-test and Anova. SPSS Software was used. The results of study showed that 66.7% pregnant women had periodontal disease and 92% pregnant women in third trimester had periodontal disease. There was a significant relation between CPITN and gestational age, education level, economic level and frequency of tooth brushing. The results of this study showed that pregnant women had higher CPITN than non pregnant women, then it might be suggested that simple preventive oral hygiene program help to maintain healthy periodontium during pregnancy.

Regarding to the prevalence of gingival recession, esthetic and sensitivity problems of denuded roots, a variety of surgical techniques have been used to cover recession type defects. This sequential matched randomized double blind clinical trial was designed to compare the clinical outcome following treatment of localized gingival recession by subepithelial connective tissue graft (SeCTG) with and without epithelial collar. Methods & Materials: Nine consecutively patients with bilateral 24 Miller class I gingival recession in non - molar teeth, were participated in this study. The surgical areas were randomly selected as split mouth and were treated by SeCTG with or without epithelial collar. Clinical measurements including recession height (RH), recession width (RW), probing depth (PD), keratinized gingiva (KG), and clinical attachment level (CAL) were measured at baseline and 3 months post operatively by means of Williams probe, caliper and stent. Changes in these clinical parameters were calculated in and between groups and analyzed statistically with paired T test. Both treatments resulted in a significant decrease in RH (1.88± 0.93 mm, P<0.000 in SeCTG with collar epithelium 1.54±1.11 mm, P<0.001 in SeCTG without collar epithelium) and RW (1.62±1.38 mm, P<0.002 in SeCTG with collar epithelium 1.22±1.62 mm, P<0.024 in SeCTG without collar epithelium). The mean changes in RH, RW, KG, CAL in each group to baseline were significant. However, the amount of these variables were not significant between the two groups. The subepithelial connective tissue graft with epithelial collar offers a more convenient approach for handling and suturing as a root coverage procedure and increasing width of keratinized gingiva in Miller class I recession defects specially in fixed and removable partial dentures for abutment teeth.
